I'm having problems with entering an answer on my current homework problem. My course is online and it's asking me
For what values of the common ratio r is it possible to find the sum of an infinite geometric series? (Enter your answer using interval notation.)?
I tried using (-1,1) because |r| < 1 , but it appears as a wrong answer I'm a wrong here?
r could be between -1 and 1
As such, there is no accounting for the quirks.
Only the programmer knows why he/she thinks that answer is correct even though it is not.
Online courses appear to be the future of education.
If that is correct, we are doomed. In most cases, programmers are not good instructors.
